Sessions: Actually how much data is 4KB? - El Forum - 02-14-2008 [eluser]CI Nick[/eluser] Just reading about the sessions class and noted the maximum of 4KB that the cookie can hold? Is this going to be an issue if you were, for example, going to store cart contents (product id & qty) in the encrypted cookie? Can someone quantify how much 4KB of data actually is? Thanks. Sessions: Actually how much data is 4KB? - El Forum - 02-14-2008 [eluser]systemsos[/eluser] When using sessions, the cookie actually only contains the Session_ID. Everything is stored on the server.

They allow to store user data in a DB table, and the cookie only contains a session ID. This way you can store whatever you want, and it's way more secure. Sessions: Actually how much data is 4KB? - El Forum - 02-14-2008 [eluser]Elliot Haughin[/eluser] To answer your first question... 4KB is quite a good size actually. It is estimated that a kilobyte can accommodate about 1/2 of a typewritten page. Therefore, one full page requires about 2 kilobytes. And 4KB could store about 2 pages of text. Hope this gives you an idea of 'how much' stuff you can get into 4KB Sessions: Actually how much data is 4KB? - El Forum - 02-14-2008 [eluser]Isern Palaus[/eluser] This is 4Kb:

Sessions: Actually how much data is 4KB? - El Forum - 02-15-2008 [eluser]systemsos[/eluser] My Edit from another post: CI's session class doesn't store user data in the session, it stores it in the cookie... so, why's it called the session class? I'm confused, there must be something I'm not reading right in the code for the class
